The former Hamilton County Board of Elections worker convicted last year of illegal voting and sent to prison for five years was released Tuesday because of mental health issues.

Melowese Richardson, 58, was too ashamed to mention her bipolar disorder last year and forbid her attorney, Bill Gallagher, from including it as part of her attempt to elude prison. But after she was convicted last spring of four counts of illegal voting, her new attorney appealed the case and raised the issue.

When he sentenced Richardson last year, Common Pleas Court Judge Robert Ruehlman made stinging comments about Richardson, her criminal history, her violation of elections board rules and Ohio laws and her selfishness.

"I was not aware of her mental health issues" at that time, the judge said Tuesday, because she refused to allow her attorney to mention it.

After her new attorney, David Singleton, took her case on appeal, he presented her mental health history to Prosecutor Joe Deters. He agreed her bipolar disorder was so severe that she shouldn't be imprisoned.

"We went to Joe Deters with those records and Joe immediately recognized that it was inappropriate to have her locked up for five years when the (judge) didn't know she had mental health issues," Singleton said.

In the Tuesday hearing that lasted just minutes, Richardson said nothing except to briefly answer questions, saying she was aware of what was happening and approved.

The judge dismissed her May 2013 conviction and five-year prison sentence and allowed her to plead no contest to four counts of illegal voting, the same charges on which she was convicted. That allowed the judge to re-sentence her, placing her on five years of probation and releasing her from the Hamilton County Justice Center after eight months in prison.

Richardson's case drew national headlines last year because of the allegations of illegal voting across the country – and because she was a Hamilton County poll worker from 1998 until her arrest.

She was convicted of voting twice in the 2012 election and voting three times – in 2008, 2011 and 2012 – for her sister, Montez Richardson, who has been in a coma since 2003.

Richardson was previously convicted of threatening to kill a witness in a criminal case against her brother, of stealing, of drunken driving and of beating someone in a bar fight.

Hers was the third 2012 conviction in Hamilton County for illegal voting.

Russell Glassop, 76, of Symmes Township, submitted his wife's absentee ballot after she died in 2012. Sister Marguerite Kloos, 56, of Delhi Township, voted in 2012 using absentee ballot for another nun who died before she could cast her vote.
